Before operation, we strongly advise that you read this user manual thoroughly, storing it in a safe place along with your original receipt of purchase, in case you should require assistance in the future. 4 // 24 Chord Electronics ULTIMA 3 | Manual _ Protection against liquids & heat 1.1 Introduction 1.2 Protection against liquids & heat 1.3 Dismantling & radio frequency interference 1.4 Connecting your equipment 1.2 The ULTIMA 3 is not protected against liquids of any kind. Never place containers of liquid on ULTIMA 3. Never allow ULTIMA 3 to come into contact with moisture or liquids; doing so could result in electrocution or damage to the ULTIMA 3 internal circuitry. Be aware that liquids, including water that has dried, can leave minerals that can affect the PCB and other components, which could eventually lead to oxidisation and short-circuiting. If the ULTIMA 3 comes into contact with moisture or liquids, immediately disconnect from the mains power supply, and connected equipment, and contact Chord Electronics for further advice. The ULTIMA 3 has internal thermal protection that will cut the power supply if reached. Never operate the ULTIMA 3 near sources of heat or naked flames as this will decrease the lifespan of the internal components. It is advised that you do not operate the ULTIMA 3 in an area of direct sunlight or on top of significant heat- producing devices. Please be aware that it is entirely normal for the ULTIMA 3 to become warm during use, particularly within a stacked configuration. If you are concerned about the temperatures, please switch the device off and consider a different placement. 5 // 24 Chord Electronics ULTIMA 3 | Manual _ Dismantling & radio 1.3 frequency interference 1.1 Introduction 1.2 Protection against liquids & heat 1.3 Dismantling & radio frequency interference 1.4 Connecting your equipment There are no userserviceable components within the ULTIMA 3 or its power supply. Dangerous voltages/currents exist within the ULTIMA 3 and its power supply, posing a severe risk of electrocution and/or fire. Never attempt to open, dismantle or apply internal thirdparty devices to it or insert anything other than the listed interconnects or speaker cables within this user manual. If the ULTIMA 3 develops a fault or the casework becomes damaged, immediately disconnect from the mains power supply and connected equipment and contact Chord Electronics for further advice. With a thick, solid aluminium chassis, the ULTIMA 3's casework largely protects the sensitive internal circuitry from radio frequency interference. However, for optimal performance, it is recommended that the following points are observed: 1.Consider placing the ULTIMA 3 away from wireless routers. 2.Separate the ULTIMA 3 from amplifiers using toroidal transformers. 3. Operate mobile phones at a distance to avoid interference. Although the ULTIMA 3 is largely shielded, it can generate radio frequency interference that may have an effect on radio and television reception. If this occurs, please reconsider your placement. 6 // 24 Chord Electronics ULTIMA 3 | Manual _ 1.1 Introduction 1.2 Protection against liquids & heat 1.3 Dismantling & radio frequency interference 1.4 Connecting your equipment Connecting your equipment 1.4 Before connecting the ULTIMA 3 to any equipment, consult the manufacturer's user guide to confirm compatibility. When connecting the ULTIMA 3 to any equipment, make sure that all devices are off, including the ULTIMA 3.

ULTIMA 3 has no ability to switch between the inputs therefore, only one must be used. Invertion relates to the phase of the incoming signal. During normal operation for Chord Electronics products, the use of the inverted inputs is advised, however, you may select noninverting if desired by removing the cap covering the XLR input. If you remove the cap please take great care to connect both amplifiers with the same invertion to avoid an out-ofphase configuration. If using ULTIMA 3 with older models of Chord Electronics monoblocks please note the inputs will be reversed. WARNING: ULTIMA 3 must be connected to a dedicated preamplifier, or a device capable of attenuating its output. Failure to attenuate the volume before it enters ULTIMA 3 could result in irreversible hearing damage, speaker damage and could void the warranty.

Both positive speaker terminals originate from the same source, as does the negative speaker terminals. Do use the additional two postive and negative terminals if you wish to bi-wire your speakers. In order to connect ULTIMA 3 to loudspeakers, use high-quality loudspeaker cable terminated with 4mm banana plugs or 6mm spades. Bare wire can be used, but it is not recommended. Connect the black (negative) terminal from ULTIMA 3 to the negative terminal on your loudspeaker and the red (positive) terminal from ULTIMA 3 to the red positive terminal on your loudspeaker. Repeat if you wish to bi-wire the same speaker.

To power-on ULTIMA 3 press the large power button once until you feel a click. ULTIMA 3's power button will now change to a green colour whilst it begins its initial safety checks. During this phase do not increase the gain on the input device as you cannot determine its final amplified volume which can damage the connected speakers. Once the amplifier has passed the safety check and is operational, after approximately ten seconds, the amplifier will display a teal colour. 12V Trigger: A 12V trigger can be used to remotely turn ULTIMA 3 on or off. Please refer to the below diagram to correctly wire your 12V trigger. When a 12V trigger is sensed by ULTIMA 3 the colours displayed on power button will be different. During standby the large power buton on the front panel will illuminate an orange colour, however just like the power sequence without the 12V trigger a green colour will be displayed once you switch the unit on and it performs its safety checks. You should still not increase the gain on the input device. Once the amplifier becomes operational the power button will display a continuious purple glow. WARNING: In the rare event that a fault is detected the amplifier will switch itself off. If this occours discontinue use immediately and seek help from your Chord Electornics retailer. 0V / Ground +5V to +12V 21 // 24 Chord Electronics ULTIMA 3 | Manual _ Earthing issues in Europe 4.6 4.1 Placement 4.2 Connecting ULTIMA 3 to ancillary equipment 4.3 Audio inputs 4.4 Audio outputs 4.5 Power-on sequence and 12V trigger 4.6 Earthing issues in Europe 4.7 Adjusting the brightness of the LED`s In some European countries, a hum or buzz may occur if the amplifier is connected to mains sockets that do not have an earth or adequate earth.
